PLEASE HELP! I need EXACTLY this same type of diagram for my 84' 380SL, the one that shows the wire color and placement of each wire going into this 15 pin connector. I desparately need help here if anyone has this diagram. I am in MA also and Noooooo help from 3 dealerships I tried...UGH! Is this situation with the dealers unique to us here in the NE or is it prevalent everywhere? Many thanks in advance for any and all help, Jeff
